Correlation functions of cold bosons in an optical lattice
arXiv:cond-mat/0407022 · doi:10.1103/PhysRevA.70.063622
Abstract
We investigate the experiment of collapses and revivals of matter wave field in more detail. To this end we calculate the lowest-order correlation functions of the Bose field. We compare predictions of the total Fock state with the commonly used coherent state approximation. We also show how to observe an interference pattern for the celebrated Mott state.
